If you live in Manhattan and want to see a sight you'll never forget, then travel to West Broadway and Grand Street. Look up and you'll see the disturbing 3D face of the Jell-O pudding man.

The countenance is part of a promotion by Jell-O and ad agency Crispin Porter + Bogusky. The agency designed this billboard which pings Twitter and either frowns or smiles based on the global mood of the service.

It's a neat idea that would work well if the face wasn't so deranged. It's almost a guarantee the creepy smile and fat frown will be the centerpiece of your next nightmare. If you dare, there's also a companion website that's equally odd. [PSFK via Oh Gizmo!]
